EDGE REENFOBCEMENT FOB SCREENS AND THE LIKE.

Application filed December so, 1921. Serial lea-52am.

To all whom it may concern:

Be it known that I, LnoroLo GUGGENBER- GER, a citizen of the United States, and a resident of Hastings-on-Hudson, Westchester County, New York, have invented a new and useful Improvement in Edge Reenforcements for Screens and the like, of which the following is a full, clear, and exact description.

My invention relates to improvements in reinforcing attachments for wire screens,

window shades, and similar structures which are operated in a window or similar opening, and which are rolled u or slide in the said opening. An objectlon to rolling screens has been that the are so likely to get wrinkled or distorte on one or both sides near the edges, and once this occurs, the screens never get back to their fiat smooth shape. The same difliculty is had in curtains or shades, particularly shades for car windows, in which the edges of the shades run in guide slots. The shades 'are' inclined to blow out or get out of place by rough usage, and it is diflicult to get them back in place. Moreover, the flapping of the shade is apt to distort it and be objectionable generally. The object of my invention is to overcome these difiiculties, and to roduce an attachment which is simple an inexpensive, and can be easil applied to the edges of the screen, sha e, or the like, so that the material to which the attachment is applied will wear much longer, and will be generally better-for the purpose intended. In carrying out this idea I" employ a strip of thin'metal at each edge longitudinally of the material to which it is applied, and apply the strip in sucha way that it will not add materially to the bulk of the screen, shade, or article to which it is applied. This metal strip should be sufiiciently springy to retain its shape, but capable of being easily rolled up with the screen or shade to which it is applied. It can be of an desired width according to the use to w ich the article is to be put,

- and when applied, it serves not only to keep the screen or shade in shape, but to finish the raw edge which might otherwise occur, and. as the strip adds a finish to the article, it obviates the necessity of other-' wise finishing the edge, so that it serves the double purpose 0 an edge finish and reenforcement. Thiswill be better under-.

I dow frame haying a screen therein provided with my improvements.

F gure 2 13 8. vertical section thereof.

Flgure 3 is an enlarged broken front v ew of one part of a screen fitted with my reenforcement.

Flgure 4 is a view similar to Figure 3, but showmg a slightly modified form of fastening chp. I

Figure 5 is a view of a partially opened cllp for fastening the edge reenforcement to the screen or shade, and Figure 6 is a detail sectional plan showmg how the structure illustrated in Figure 4 is used.

By way of example I have shown my invention applied to the edges of the screen .10, but obviously this screen can be any flexible material such as would be used in a VYlIldOW frame or the like, whether metalllc, woven, textile, or other fabric. The manner in which the screen or shade operates is not material, but I have shown the screen running on a roller ,11 at the top of a window, and sliding in slots in a window frame 12. Structures .of this kind.

usually enter slots in a window frame for guiding purposes.

In the drawings I have shown metallic fastening strips 13 of thin sheet spring metal running along the edges of the screen 10, and these are sufliciently sprin to. retain their shape, and if they are f astened securely to the adjacent material, they will obviously keep the material from kinking, twlsting, or getting out of shape.

It is evident that the reinforcing strips might be fastened to the edges of the material in very many ways without affecting the invention. I have shown a convenient way in which metallic clips 14 are used, these being doubled in the middle as shown at 15 so as to embrace the strips 13, and each clip has laterally projecting points 16, one member of which can be passe through the material of the screen or the like and i doubled over upon the other member of the clip, as clearly shown in the drawings. The metal of the clips 14 is soft enough to bend without breaking, and so the clips can easily clasp in the middle portion the edge strip 13, the opposed members of the clips being then pressed firmly against the web of' the screen or shade. The members 16 can be turned up so that they will pierce the Web, and their free ends can be doubled over and pressed down upon the second member of the clip so that the two members of the clip are firmly fastened together with the strip 13 and the web of the screen between them.

In some cases it is desirable to have the edges of the screen, shade, or the like engage a guide which will prevent the displacement of the article. With my invention this is not necessary, as the reinforcing metallic strips 13 of springy material serve to keep the article to which they are attached taut and straight, and so the article can run in a plain slot or groove without much danger of displacement; but if desired the screen or shade can be made to engage a device to keep it in place as well as if the fastening strips were not used. A convenicnt way of accomplishing this result is to have the clips 17 like those already described but slightly longer, so that the outwardly projecting part may be doubled over. laterally to form a hook 18 which can slide behind a suitable guide 19 as in Figure 6. No attempt is made to illustrate any necessary form pf guide, but the illustration makes it clear that the fastening clips can he used to prevent the displacement ofthe shade or screen to which they are attached, and it is obvious that the projecting clips can be bent to any desired shape so as to fit any preferred form of guide. It Will be further observed that as the clips are spaced apart and are narrow. they will not interfere with the rolling up of the article to which they are attached, but will serve to bind the article firmly to the reinforcing edge strips 13.

These reinforcing strips have been thoroughly tried out, and it is found thatthey serve perfectly to keep the article to which they are attached taut and straight. and to provide against its being twisted or bent out of shape. and that they further serve to keep the article of which they form a part in its guide slots.

In the claims I have referred to my improved rcenforcement as applied to screens,

the body and substantially in the plane of the body. said strips and body portion being placed edge to edge, and fastening clips overlapping a substantial part of both sides of the body to which they are secured and engaging the strips, with the outer portions of said clips bent laterally to form guiding devices.

2. As an improved article of manufacture, a screen, comprising a body, thin flexible springy metallic strips at the side edges of the body and substantially in the plane of the body, said strips and body portion being placed edge to edge, and fastening clips overlapping a substantial portion of both sides of the body and clamped thereto, said clips embracing the aforesaid metallic strips and having their outer portions formed into guiding devices.

3. As an improved article of manufacture, a screen, shade, or the like, comprising a substantially conventional body portion, thin, flexible metallic springy strips at the side edges of the body, and in substantially the same plane as the body, the strips and body being arranged edge to edge, and fastening clips embracing the strips and overlapping a substantial portion of both sides of the body to which they are attached.

4. A screen. comprising a substantially conventional body portion, thin flexible springy metallic strips at the side edges of the body, the strips and body being arranged edge to edge, and members fastening the strips to the body and projecting from the outer edges of the strips to engage complementary guiding devices.

A screen, comprising a substantially conventional body, reinforcing edge strips at the sides of the body, said strips being arranged edge to edge with the body, and said strips also being formed of thin springy metal, and fastening clips embracing the strips and engaging the body, said clips being prolonged at their outer extremities to form guiding devices.
